A Novel Technique for Secure Communication in Cryptography

Abstract: Securing the information from attackers is very important key aspect in today's life. Many cryptographies algorithms are used in data transmission security. Many encryption algorithm like AES, DES, and RSA etc. have been proposed by researchers. Nowadays so many cryptography attacks are there so, we need to improve security level of algorithm which will also make algorithm complex .key is a very important factor in security algorithm. Two types of keys are available in cryptography 1. Symmetric key 2. Asymmetric key. In this paper we have proposed a new key algorithm of 128 bits which enhance the security level. It is combination of AES, DES and IDEA algorithm.

Keywords: AES, DES, IDEA, Encryption.
